What would be the best way to allocate: 1) a VM page whose physical address falls within a certain boundary, and 2) a VM object whose pages are contiguous in physical address space?
Background: The !@*%^*!&#^%*&!#^$!@ Intel 810/815 graphics controller requires its instruction and hardware cursor buffers to reside within first 32MB and 512MB of *physical* memory space respectively. :( :( ;( The XFree86 driver assumes the Linux memory model (virtual addr == physical addr), so it runs on Linux, but not always on FreeBSD.
